Azuchi Castle Ruins
In 1576, Nobunaga broke ground to construct Azuchi Castle. However, there was a huge crisis. His staff and the surrounding daimyo were not supplying him with enough quality stones for the castle walls and fortifications. The story goes that Nobunaga ordered his father's grave stone to be removed from Banshoji Temple (located in Nagoya) so it could be used for the castle construction. It was said that the grave stone was laid amongst the rocks at Azuchi. This scared the living hell out of the surrounding daimyo that Nobunaga would force them to use their families grave stones for the Azuchi project. Out of fear, the surrounding daimyo and staff found suitable stones for Azuchi Castle.
I will be honest with you, I do not believe this story is true. That being said, it is an interesting story. It might have been made up and the story might have been used to spread fear among the staff and the surrounding daimyo. In my humble opinion, the story was used to spread fear to get the suitable stones quickly as possible.
Tenka no tame!
